CNC Spindle Motor 2.2 kW, 24000 RPM, 380V Water Cooled ER20

The 2.2 kW Water-Cooled CNC Spindle Motor is a professional-grade solution designed for continuous, high-precision machining in demanding industrial environments. Delivering 2.2 kW of power on a 380V architecture, this motor provides a stable 0.87 Nm of torque at a peak speed of 24,000 RPM. It is optimized for high-speed cutting, precision milling, and industrial routing across a variety of substrates. The integrated water-cooling jacket ensures superior heat dissipation, protecting the high-precision P4 grade bearings (2x 7005 front and 2x 7002 rear arrangement) from thermal runout during long production cycles. Equipped with a versatile ER20 collet system supporting tool shanks up to 13mm, this 5.4 kg motor provides the mechanical rigidity and rotational accuracy necessary for professional machine tool centers and high-throughput production lines.

Technical FAQ & Operational Guide

Does this 2.2 kW motor require a specific voltage setup?

Yes, this model is designed for 380V AC input. It must be paired with a 3-phase Variable Frequency Drive (VFD) that matches this voltage to operate correctly at the required 400 Hz frequency.

What is the benefit of the ER20 collet over ER11 or ER16?

The ER20 collet system is more robust and supports larger tool shanks—up to 13mm. This allows for the use of larger material removal bits and provides higher clamping force, which is essential for the 2.2 kW power rating when performing heavy-duty milling.

How often should I check the water cooling system?

The water cooling system is vital for protecting the P4 grade bearings. We recommend checking coolant levels and flow daily before starting production. For industrial use, using a water chiller with flow alarms is the best way to ensure the long-term reliability of the motor.

How is the rotational balancing calibrated on this spindle motor?

Every spindle motor is dynamically balanced in accordance with the ISO 1940 balancing standard to guarantee vibration-free running and maximum stability at high RPMs.

What are the runout tolerances of the shaft and collet interface?

The internal shaft taper maintains a runout accuracy tolerance of under 0.003mm (3 microns), maintaining precise tool concentricity and preventing premature cutter wear.

What cooling precautions are built-in to prevent heat exhaustion?

Built-in temperature dissipation channels support continuous water/liquid cooling circulation or forced fan airflow, preventing thermal expansion of components.

Is this spindle motor compatible with standard VFD inverters and collets?

Yes, the spindle supports direct electrical integration with standard variable frequency drives (VFD) and accepts industrial ER collets (ER11, ER20, ER25, or ER32) to match standard toolholder dimensions.
